Abstract

An electrically actuated flow control device for use with an electrical household appliance includes a single body defining first and second flow passages. Inlet ends of the flow passages connect to pressurized sources of hot and cold water, and outlet ends of the flow passages connect to hoses for delivery of hot and cold water to the appliance. Hot and cold water actuators are each adapted to move between a first position resisting flow through the flow passages and a second position permitting flow through the flow passages. A sensor detects whether current is being drawn by the appliance, and a controller controls the positions of the actuators dependant upon whether current is being drawn. The inlet ends of the flow passage each include a connector arranged at a desired spacing from each other corresponding to the connector spacing in a mechanical flow control device.
